IMPROVEMENT IN LABELING-MACHINES.

Specification forming part of Letters Patent N 0. 181,635, dated August 29, 1876; application filed July 15, 1876.

To all whom it may concern:

Be it known that I, Gnonen H. BURROWS, of Boston, county of Sufiolk and State of Massachusetts, have invented a new and Improved Labeling-Machine, of which the following is a specification:

Figure l is a side elevation v of my machine with portions broken away to show the internal construct-ion more clearly. Fig. 2 is a plan. Fig. 3 is a transverse section on line 90 :r, Fig. 1.

My invention relates to apparatus forlabeling packages; and it consists of a combination of levers, worked by suitable gearing, and paste-rollers and pastetroughs, in such a way that by moving a hand-lever, the rollers charged with paste are thrown out of the pastetroughs' onto the ends of the label and back again into the troughs. It also consists of a platform carrying the labels, which is counterbalanced by a weight in such a way that the pile of labels placed on the platform is always held by the-counterbalance against a retaining-lip,"so that the upper label in the pile is always at a given point. It further consists of a guard thrown over the free end of the label by the action of one of the paste-rollers. The whole is arranged and operated as hereinafter more fully described.

Referring to the drawing, A is afraine supported on legs, or otherwise, in an inclined A slide, a, is fitted to ribs at the top of the frame, and has a standard, 12, attached to it, that supports a paste-trough, B. c is an inclined shelf or table, thatis attached to the ends of the trough, but is narrow enough,

to leav e a space at each side, between it and the sides ofthe trough. A standard, 0, is rigidly fixed to the frame A andsupports a paste-trough, D, which is similar to the one just described, but has a swinging guard, d, that is hinged at e, that is thrown over the free ends of the label by the paste-roller. Fingers f are attached to the swinging guard d,that support the roller L when it is in the paste-trough. E E are bars, that support a table, F, upon which the labels G are placed with their backs or unprinted side uppermost.

A weighted lever, H, having a fulcrum, at 1,.

is connected with the bar E, and counterbalances the table F and. tables G. A lip, f,

is turned on the edge of the paste-trough B, against which the labels are pressed by the weightedleverH. Aclamp,g, is placed on the bar E, which allows the bar to move upward,

but holds it so that the additional weight of or cover, 70, which is placed on a pin, 1, that projects from the side of the arm M. The said arm swings on a pivot, m. N is a spur-wheel turning on a post, '10. A weighted pawl, q, is pivoted to an arm, 1", that swings on the post p, and it engages with a ratchet, 1", attached to the spur-wheel N. A weighted lever, 0, having its fulcrum at s, is connected with the pawl-arm r by the rod t. P is a short shaft placed in a suitable support, and carrying the pinion a, which meshes With the wheel N and the cranks '0 c, which are arranged on the shaft in positions diametrically opposite. The crank U is connected with the arm M by a rod, 20, and the crank c is connected with the arm 70 by the rod 00. Q Q are guides for the ends of the labels, and R R and S S are guides forthe sides of thelabels. guide for the package to be labeled, that is divided diagonally at 3 One part of it is attached by means of brackets to the guide S, and the other part is attached in the same way to the guide S. The guides Q, R, and S, are attached to the adjustable part a of the supportingframe, so that as the frame is extended to take in a longer label the said guides will go with the movable part. a is a weighted lever pivoted to the guide R, which prevents the labels from slipping over the top of the said guide. rests on the paste-trough B, and is capable of being raised by the guard h, as it is moved out of the trough. A finger, d, prevents the cover from dropping behind the guard It. At 1) b are fingers attached to the. levers K and M to keep the guards h and 7c from rising above a prescribed distance. A guide, V, is supported on standards V W, and is bent at i. i I} i ll- Tisa A cover, U, is hinged at a, and

. revolution to the cranks v "0.

a right angle at each end and passes through sleeves c 6'. It is shouldered to bear against springs in the sleeves, and is prevented from being thrown out too far by pins that pass through projecting ends of the guide. The standard W is made adjustable by the slot and screw 6.

The operation of the machine may be described as follows: A quantity of labels, Gr, being placed on the table F are held by means of the weighted lever H against the lipf, and the paste-trough B and D being charged with aste the lever O is ressed down causin the wheel N to turn sufficiently to give one This motion is communicated to the arms K and M, which, in turn, move the rollers J and L, which are charged with paste, so that they touch opposite ends of the label, applying enough paste to stick the label to the package, and are returned to thepaste-troughs. The roller L, in its passage out of the trough D, moves the guard d on the end of the label, retaining it in its place until the paste-roller leaves it. The case or package is now placed between the guides T and Y upon the pasted portion of the free end of the label; it is then rolled toward the lower end of the machine, carrying the label with it. As it passes the lip f it draws the end of the label from under the lip and rolls over the cover U, and is carried away by a chute or by hand. This operation can be rapidly repeated. The lever H constantly feeds the labels up against the lip f.

Having thus described-my inven tion, I claim as new and desire to secure by Letters Patent- 5. The'cornbination of the guards h, roller J, finger b, andlever K, as shown and described.

6. The combination of the diagonally-divided guide T, and the guides S S, as shown and described.

7. The combination of the guides Q R S, lever K, paste-trough B, and movable part a of the frame A, substantially as shown and described.

8. The combination of the weighted lever z, and guide R, as shown and described.

9. The guide V bent at the ends, passing.

through sleeves and supported by shoulder and pin against springs, as and for the purpose specified.

10. The combination of the hinged cover U, finger d, paste-trough B, and roller j, substantially as described.
